You’re driving on a motorway and see a lorry which has stopped in the right-hand lane. The lorry is displaying a sign. What does it mean?

Explanation: This sign on the back of a lorry tells you to pass it on the left rather than the right. You'll often see this near roadworks on motorways, particularly where they need to work on only a small stretch of the road, and therefore aren't fully closing the lane.
